Universal Remote

Offline universal IR remote for Android phones with an IR blaster (built on a Xiaomi Redmi 4X). Air conditioners first; TV support follows.

Features

• Find my AC: pick the brand (popular Vietnamese-market brands are suggested first) or let auto search try every code. The phone has no IR receiver, so you confirm when the AC beeps; a power-off check confirms the match.
• AC remote: temperature, mode, fan speed, swing and turbo, with each AC's last state remembered.
• 13 AC codes: Daikin, Panasonic (DKE, JKE), LG (LG2, LG), Casper / Electra, Samsung, Toshiba, Mitsubishi Electric, Gree (YAW1F, YBOFB), Coolix (Midea-made units), Midea. Each encoder is checked byte for byte against IRremoteESP8266 test vectors; Electra is also checked against 727 real Casper SC-09FS32 captures from SmartIR.
• TV groundwork: NEC, Samsung32, Sony SIRC, Panasonic and Pronto encoders plus IRDB code sets.
• IR diagnostics: emitter check, carrier ranges, test bursts.
